BUSINESS OPERATIONS DEPARTMENT SAFETY BRIEFING OFFICE ERGONOMICS E.H. Winkler August 16, 2010
OFFICE ERGONOMICS Good Working Positions Hands, wrists and forearms are straight, in-line and roughly parallel to the floor. Head is level, or bent slightly forward, forward facing, and balanced. Generally, it is in-line with the torso. Shoulders are relaxed and upper arms hang normally at the side of the body. Elbows stay in close to the body and are bent between 90 and 120 degrees. Feet are fully supported by floor or footrest. Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly. Knees are about the same height as the hips with the feet slightly forward. Note: Sitting for prolonged periods is not healthy – Periodic standing/stretching is recommended. Avoid repetitive motions. Ergonomically Adjusted Chairs The backrest should conform to the natural curvature of your spine and provide adequate lumbar support. The seat should be comfortable and allow your feet to rest flat on the floor or footrest. Armrests, if provided, should be soft, allowing your shoulders to relax and your elbows to stay close to your body. The chair should have a five-leg base with casters that allow easy movement along the floor. Note: Ergonomically designed chairs are available in the PPPL stockroom.
OFFICE ERGONOMICS Ergonomically Designed/Positioned Monitors Place monitor directly in front of you – 20-40 inches from body. - Too far away results in leaning forward. - Too close causes eye strain. Place monitor so top line of screen is at eye level. - Placing monitor higher will result in neck strain. Place monitor perpendicular to window. General Work Area Desk surface should allow you to place the monitor directly in front of you, at least 20 inches away. Avoid storing items such as a CPU, under desks. Desks should be able to accommodate a variety of working postures. Arrange your office to minimize glare from overhead lights, desk lamps, and windows. Maintain appropriate air circulation. Avoid sitting directly under air-conditioning vents that “dump” air right on top of you. Maintain a clear work area. Cluttered work areas force work-arounds, resulting in awkward body motions. Minimize glare coming from bright overhead light and windows. - Use a screen filter, if needed.
